Re: Printing barcode

[Leleux@xxxxxxxxxxxx]

As someone else stated well, barcode printing can be accomplished
many ways.

1.   Using native RPG primitives, you can print barcodes to an IPDS
     printer.  It's purely a DDS function as shown below.

 ENAME     R           1  4
 EMPNOZ         6      2  8
 EMPNOB         7      3  4BARCODE(CODE3OF9 2 *NOHRI)

     Above is a DDS stub from a program that prints specific employee
     badges upon demand.  Note that the Empno? field is shown twice,
     once for regular print, once for bar code.  The difference in length
     is for the checkdigit associated with empno (MAPICS).  The nohri
     stands for no human readable, as we find it too small.
     The 2 between is character height, IBM is pretty good in the manual
     about this stuff.

2.   A company called cablenet makes an IPDS converter that fits nicely
     between your twinax and an HP laser's parallel connection.  Get a
laser
     with both a NIC and parallel and you've a great service combo!
     (I think black box makes (re-packages) the device as well)

     You should have this for MAPICS routers (travellers) anyway!

3.   Use a 'pc' based Thermal Transfer printer, such as Zebra.
     Encode ZPL (Zebra printer language) within the DDS and
     put a protocol converter between the twinax & printer
     (EBCDIC to ASCII) and your off!


1  1'~CC?'
2  1'?XA'
3  1'?FO60,40?GB1125,1055,4?FS'
4  1'?FO580,40?GB0,215,4?FS'

5  1'?FO80,53?CFF?FDFROM:?FS'
6  1'?FO80,83?A0,30,30?FDSHUR-LOK CORP.'
6 35'?FS'
9  1'?FO325,30?XGR:SLLOGO1.GRF1,1?FS'


     Above is a sample of DDS for ZPL, its drawing borders, incorporating
     text & variables, barcodes, and even graphics such as logos!

It can get cumbersome, but there are ways of accomplishing within RPG, this
is appealing to me because its all background, no interactive, spool/screen
scrapes, no batches and best of all NO LICENSING FEES!!!!!!!


Hope this wasn't too low level, can supply full examples if you like.
